Sera GH Test Kit

  • makes it easy to monitor the total hardness (GH) in freshwater and saltwater aquariums as well as ponds.

For approx. 420°dGH. In case of too low GH values we recommend sera mineral salt. High total hardness levels can be lowered by mixing in R/O water. For creating soft water we recommend adding sera blackwater aquatan or filtering through sera super peat.

  • Instruction Manual
  • Reagent – 15ml (dropper bottle)
